I’m a software developer. I live in Montreal. I sometimes give talks. Most of my income comes from my programming zines business Wizard Zines. I have one main opinion about programming, which is that deeply understanding the underlying systems you use (the browser, the kernel, the operating system, the network layers, your database, HTTP, whatever you’re running on top of) is essential if you want to do technically innovative work and be able to solve hard problems.

Hello! Recently I needed bike lights for my bike. And I remembered that I already had rechargeable bike lights that I bought ten years ago, that I hadn’t tried in a long time. I tried to recharge them, but after fully charging them, they only worked for maybe 5 minutes before they turned off again. I don’t know much...
Hello! I’m on a funny journey right now where I’m trying to learn how to make websites in a sort of 2010 style, where I have an SQL database and render some HTML on the backend. It’s kind of an interesting journey because it doesn’t necessarily feel “easy” to me to make websites in this way: I never learned how to...
Hello! I’ve been working on a Django site recently, and I decided to use SQLite as the database. When I was getting started with using SQLite as database for a website I read a bunch of blog posts about how it is totally fine to use SQLite in production for a small site and I think it is totally fine, but what I did...
Hello! 8 years ago, I wrote excitedly about discovering Tailwind. At that time I really had no idea how to structure my CSS code and given the choice between a pile of complete chaos and Tailwind, I was really happy to choose Tailwind. It helped me make a lot of sites! I spent the last week or so migrating a couple...
A while back I decided to stop using Tailwind for new projects and to just write vanilla CSS instead. But one thing I missed about Tailwind was the colour palette (here as CSS). If I wanted a light blue I could just use blue-100 and if I didn’t like it maybe try blue-200 or blue-50. I’m not very good with colours so...
Hello! One of my long term projects on here is figuring out how to write frontend Javascript without using Node or any other server JS runtime. One issue I run into a lot in my frontend JS projects is that I don’t know how to write tests for them. I’ve tried to use Playwright in the past, but it felt slow and...
Hello! My big takeaway from last month’s musings about man pages was that examples in man pages are really great, so I worked on adding (or improving) examples to two of my favourite tools’ man pages. Here they are: the dig man page (now with examples) the tcpdump man page examples (this one is an update to the...
Hello! After spending some time working on the Git man pages last year, I’ve been thinking a little more about what makes a good man page. I’ve spent a lot of time writing cheat sheets for tools (tcpdump, git, dig, etc) which have a man page as their primary documentation. This is because I often find the man pages...
Hello! One of my favourite things is starting to learn an Old Boring Technology that I’ve never tried before but that has been around for 20+ years. It feels really good when every problem I’m ever going to have has been solved already 1000 times and I can just get stuff done easily. I’ve thought it would be cool to...
Hello! This past fall, I decided to take some time to work on Git’s documentation. I’ve been thinking about working on open source docs for a long time – usually if I think the documentation for something could be improved, I’ll write a blog post or a zine or something. But this time I wondered: could I instead make...
Hello! Earlier this summer I was talking to a friend about how much I love using fish, and how I love that I don’t have to configure it. They said that they feel the same way about the helix text editor, and so I decided to give it a try. I’ve been using it for 3 months now and here are a few notes. why helix:...
Hello! After many months of writing deep dive blog posts about the terminal, on Tuesday I released a new zine called “The Secret Rules of the Terminal”! You can get it for $12 here: https://wizardzines.com/zines/terminal, or get an 15-pack of all my zines here. Here’s the cover: the table of contents Here’s the...
